Epa mats ria benefits.
The most likely immediate.
Typically an ria is structured similarly to an eia except that a benefits analysis of the rule is included along with an estimation of the net benefits.
When epa issued the supplemental appropriate and necessary finding in 2016 its preferred approach to considering cost was not to perform a cost benefit analysis although it did include as an alternative a cost benefit analysis.
Epa is likely to soon issue a final rule withdrawing the appropriate and necessary finding that underpins the mercury and air toxic standards mats.
Indeed these projected co benefits comprised the overwhelming majority approximately 99 9 percent of the monetized benefits of mats reflected in the epa s ria 36 billion to 89 billion.
The epa estimated in the mats ria that the annualized mercury related health benefits of reducing mercury emissions would be less than 10 million.
The costs and benefits associated with mats are discussed in detail in the february 16 2012 final mats rule.
Instead epa sought to ground its approach in its understanding of the clean air act s mandates with respect to hazardous air pollutants.
As mentioned above we used the available 2014 emissions and air quality modeling for the csapr to update the benefits of the csapr for 2016.
Epa likely will leave mats in place and determine that after analyzing remaining risks from power plant mercury and air toxics emissions no further reductions are required.
Recent studies that account for more pathways of methylmercury exposure and additional health effects suggest that the monetized benefits of reducing power plant mercury emissions in the u s.
July 17 2020 epa finalized minor revisions to the electronic reporting requirements for mats.
Mats ria we did not perform air quality modeling for the final mats scenario.
The impacts of mercury emissions on human health and the environment are well understood.
May 22 2020 epa published a final revised supplemental cost finding for mats and the clean air act required risk and technology review.

The epa projected that the co benefits associated with reducing these non hap pollutants would be substantial.
Regulatory impact analysis for the final mercury and air toxics standards.
